How is the water resistance of colored copperplate label paper?

The water resistance of colored copperplate label paper varies depending on the specific product and its treatment process. In general, color copperplate label paper without special treatment does not have excellent water resistance. The following is a detailed analysis of the water resistance of color copperplate label paper:

First, basic water resistance

Color coated paper itself is a paper made of bleached wood pulp coated with a layer of white chemical raw materials and then calendered. It has the characteristics of smooth surface, high whiteness, uniform distribution of paper fibers, uniform thickness, small scalability, and good ink absorption and inking performance. However, as far as water resistance is concerned, ordinary colored coated paper does not have a particularly strong waterproof function. If the label paper meets water, the powder on its surface may fall off, resulting in the original printing effect cannot be maintained for a long time.

Second, special treatment to improve water resistance

In order to improve the water resistance of colored copper label paper, some manufacturers use special treatment processes, such as laminating. The film can form a protective film on the surface of the label paper, effectively blocking water, thus enhancing the water resistance of the label paper. For example, recently, some companies have successfully developed a double copper paper coated label solution with excellent water resistance, through the innovative coated adhesive formula, so that the double copper paper coated label can keep the paper film bond stable even if soaked in water, no signs of separation.

Third, application scenarios and selection suggestions

1.Application scenario: Color label paper is widely used in a variety of commodity packaging, propaganda color pages, calendars, business cards and other fields. For scenarios that require high water resistance, such as outdoor advertising and aquatic product packaging, it is recommended to select a color copperplate label paper that has been specially treated (such as film coating).

2.Selection suggestion: When selecting color copperplate label paper, it should fully consider whether its water resistance meets the actual needs. If you need to be exposed to moisture for a long time, it is recommended to choose a waterproof label paper, or consult a professional manufacturer for more specific product information and recommendations.

In summary, the water resistance of color copperplate label paper varies depending on the product and its treatment process. Color copperplate label paper without special treatment is generally water-resistant, and label paper with special treatment (such as lamination) can significantly improve the water resistance. The selection should be based on the actual requirements and application scenarios.
